Evaluate the Levels of Some Physical and Chemical Factors in Wastewater from Some Companies and Kirkuk General Hospital in Kirkuk City

Abstract

The current study aimed to evaluate the levels of some physical and chemical factors in wastewater from some companies and Kirkuk General Hospital in the city of Kirkuk. Water samples were collected from study sites, from North Oil Company, North Gas Company, Kirkuk cement plant and Kirkuk General Hospital, and for six months from September of the year (2023) AD, until February 2024, using containers Poly Athelin is 2.0 liters tight, the containers were shoved with sample water twice. Where, EC was 64600, and Salinity was 29.8 in water of North Oil Company, while TDS was 44000 in water of North Gas Company. For chemical factors, North Gas Company was the most chemically polluted compared to the rest of the samples. Where, pH was 3.67, PO4 was 36.5 ppm and NO3 was 18.6 ppm. While, highest valve of SO4 showed in water of North Oil Company and it was 1267 ppm. It is noted that the water samples collected from North Oil Company contained the highest concentration of cadmium (11.334), lead (10.355), nickel (1.356) and copper (1.579), while the water sample collected from North Gas Company contained the highest Concentration of iron (9.047) and cobalt (0.881). It’s included that the water collected from some companies and the hospital in the city of Kirkuk showed high physical and chemical contamination of wastewater, especially the northern oil and gas companies.
